AB - Cardiovascular MR offers a large range of applications. Many of these are still currently under active development by the research community, for improved accuracy and reliability. The complex nature of the cardiovascular system offers many challenges to clinicians. Its unique mixture of respiratory and cardiac motion; fast fl owing blood; and the tissue-air interface between the heart and the lungs, are just some of the diffi culties faced. Many of these challenges can result in imaging artifacts and measurement errors, which may limit the diagnostic potential of the scan or even contribute to misinterpretation. A good understanding of the physical principles behind the formation of such artifacts is imperative to identifying and minimising them. This chapter summarises, in a language accessible for a clinical readership, the most problematic artifacts specifi c to cardiovascular MR, with particular regard to their physical basis, and implications for the different sequences and applications. It includes motion (respiratory, cardiac and blood fl ow); Gibbs ringing; aliasing; chemical-shift; and B 0 -inhomogeneities.
